My Expert Take on the Best Gambling Sites – Powered by SlotsCalendar’s Unmatched Database

Currently, I can estimate that the SlotsCalendar collection of gambling sites features thousands of casino sites and platforms from all the categories you can think of. Maybe it is time to tell you a few things about how I managed to find them and what makes me the right person to tell you where to register and gamble your money as well.

First of all, let me introduce myself. I am Stoica Andrei Tiberiu and my main duty here at SlotsCalendar is to navigate the infinite internet with the purpose of finding the best gambling sites, analyze them, test them, put them to work and make sure I stress their systems. It is the only way I can guarantee that you will not encounter any technical difficulties and that you are completely safe if you decide to play on their website.

Listing online casinos as being the industry top is not an easy task and comes with great responsibility. Luckily, I have been doing this for more than 9 years, and thanks to my legislation knowledge, I can rapidly identify casinos that may represent a threat to your safety as a user.

What you should keep in mind is that all the casino sites that you are able to access from this very page are already tested and verified by me from any point of view. Their payment system is safe, their KYC works, and they have very strong encryption protocols for data protection. Not to mention the fact that all the gambling sites are licensed, regulated, and monitored by international official institutions that I personally trust. My purpose and mission at SlotsCalendar is to filter these platforms and bring them forward so that you can enjoy them.

My Casino Site Review Process

Whenever I review gambling sites online, there are several criteria I must consider. For a casino to make it to the best casino websites list, it must check all the following.

• License and Regulation: Reviews typically verify if the online casinos hold a valid license and answer to a reputable authority. I only list gambling sites that are safe and properly licensed and regulated.

Savvy Tip: I would like to emphasize that and tell you that it is extremely important to check if the online casino you are about to register at is regulated by the gambling regulators from your region. This applies especially to players from the United States. Currently, there are 22 distinct regulators from 22 different states. If the casino you are about to bet on does not own an actual license from your regional regulatory body, you should not proceed with depositing there. The same goes for European players, where a UKGC or MGA license should be enough.

• Security and Fairness: Online casino reviews also assess the measures in place to protect player information and ensure fair gameplay.

This means employing SSL encryption technology to protect your personal and financial data, as well as being constantly checked by independent testing companies.

• Game Selection: The number and variety of games offered by the online casino is also evaluated, and the more, the better.

It’s important that you have a wide range of titles and options to try so that you are entertained.

• Bonuses and Promotions: My reviews also look at the types of bonuses and promotions offered and their terms and conditions.

For a site to qualify, it must at least have a generous welcome bonus, if not some no deposit bonuses, or even a lucrative VIP program.

• Payment Options: The availability and reliability of various payment methods for deposits and withdrawals are also important.

I expect all online casinos to allow deposits and withdrawals using debit cards and wire transfers, and consider it a plus if you may use e-wallets, prepaid cards, pay-by-phone options or cryptocurrency.

• User Experience: This includes factors such as the design of the best gambling sites, ease of navigation, mobile-friendliness (either instant-play or through a casino app) and 24/7 friendly and helpful customer support.

I take these factors into consideration and combine them to give an overall rating of each casino, which helps my readers make informed decisions when choosing where to play.

What Types of Casino Sites Online You’ll Find on SlotsCalendar

The best gambling sites can fit into many different categories, each one coming with something exciting for players. While all of them are inherently great choices, it’s up to you and your personal preferences and gambling style to decide which one is right for you.

Top Casino Sites with Low Deposit Requirements

While there are no deposit bonuses that you can claim, eventually to play you will need to deposit to have more fun. This is where the best online casinos split into two categories – regular and minimum deposit casinos. Minimum deposit casinos will allow you to enjoy your favorite games for as little as $5, $3 or even $1.

Fast Withdrawal Sites

In general, it takes about 3 to 5 business days to withdraw your winnings from most casino sites, but a fast payout casino will get you your funds almost instantly or up to 24 hours.

Savvy Tip: What I have learned from my past experiences with payments and processing times is that there is a huge difference between requesting a withdrawal and actually waiting for the money to be wired. First of all, the processing time may vary depending on what payment method you use. Secondly, casinos have different times for approving withdrawal requests that are separate from the actual times you have to wait for the money to appear in your account.

To give you an example, if the casino states that withdrawals require 2 business days for approval, you should add one or two days on top of that for the payment to process.

Latest Launches on the Market

The entire online gambling world can be split into two kinds of online casino sites – new brands and established brands.

The established ones are those who have been around for 3+ years, have a large client base, have settled into their own and are already well-known and appreciated by customers.

New casino sites have just been launched, they are still in their infancy as it were, but they have a lot of enthusiasm. They are striving to become top operators and gather as many players as possible which is why here is where you will find the very best promotions on the market, the newest games and all the latest modern technology and design trends.

Casino Sites Online with Large Game Portfolios

Having a huge game selection is paramount for top rated casinos if they wish to offer all players the opportunity to enjoy themselves. This may exist in one of two ways – either they have all the most popular titles of a single game type, or they have all popular titles from all the game types.

These are all the main game types that a site could focus on, either individually or at once:

• Poker – a game that relies more on strategy than on luck, poker has multiple variants that one may play both by yourself vs the computer, with others or in tournaments. Look through our poker sites list and find yourself a suitable platform to play at.
• Roulette – invented by Pascal when he wanted to create a Perpetuum Mobile, the roulette game is seen by many people as a main symbol of gambling. With a small house edge, and guaranteeing a very fun experience, please make sure you pick a roulette site from the SlotsCalendar collection.
• Live dealer games – this type of game combines all the perks of online gambling with the socialization and unique sensations of playing at brick-and-mortar casinos. Since this service has grown a lot in the last couple of years, the SlotsCalendar team does a great job at documenting and listing all the superior-quality live dealer platforms. I personally find them to be pretty enjoyable.
• Blackjack – one of the most famous games as many have made a fortune by counting cards at blackjack (not technically illegal but frowned upon). Because it is so famous, digital Blackjack sites are constantly evolving, launching all sorts of interesting games, services and blackjack-centered activities.
• Slots – the most beloved game worldwide, slot platforms are fun, can bring you unimaginable riches and there are tens of thousands of variants available.
• Bingo – an easy-to-understand game, bingo is no longer just for old people and is gaining popularity each day. The SlotsCalendar`s page with bingo sites has at least 100 different platforms that you pick from.
• Crash gambling – a new type of game, crash gambling is an interesting option that combines slots with cryptocurrency or the stock market. I would not advise you to set a high budget for this category of games since they can get a little too volatile. However, if you feel like trying some new games for the first time, I invite you to check the crash gambling sites list SlotsCalendar experts have put together.
• Lottery – one of the oldest forms of gambling that’s still relevant today and the one that’s legal in almost all countries, even those that don’t have a regulated market yet.
• Slingo – an exciting combination between bingo and slots that’s surprisingly entertaining.

Casinos Where You Can Deposit with Your Preferred Method

The best online casino sites should have, as I have explained before on this page, a wide variety of payment methods.

While there are other classic options, such as debit cards and wire transfers, the ones you will see below are newer, better, faster and more convenient:

• Boku
• Pay by SMS
• Paysafecard
• Pay by phone
• Apple Pay
• Neteller
• Bitcoin
• Cryptocurrency

Savvy Tip: Please acknowledge that payment methods may come with different fees depending on how much or how often you deposit or withdraw. When choosing your preferred payment methods, please read their T&Cs first. If the casino is not transparent about those fees, it is a sign that you should also stay away from it.

Play on Mobile, Tablet or Smartwatch

There are very few people on this planet (and even fewer every day) who do not own a mobile device. Most people have switched from PCs and laptops for their day-to-day activities to using smartphones or tablets.

So it makes sense that technology and even entertainment would change with the times and their preferences. Consequently, almost all casino sites are mobile casino sites nowadays and permit you to play on smartphones, tablets, or smartwatches.

You only have to decide whether you prefer instant play through your browser or if you would like to try casino apps for Android or iOS.

Keep in mind that many websites offer special deals, like mobile casino bonuses, for those who choose to play on a mobile device rather than on computers as many of them are mobile-first already.

Casinos with an Extensive List of Offers

Having a large number of different kinds of casino bonuses is also a great advantage, not just for casino sites as they become the most popular online casinos because of their promotions, but for players as well.

Players can benefit greatly from bonuses (assuming that they are fair and generally good) as they can increase their bankroll, play with no risks, try new games, make bigger bets, play for a longer time, and increase their winning odds considerably.

The very best gambling sites will offer the full range of bonuses: signup (no deposit free spins or no deposit free cash), welcome bonuses, reload bonuses, cashback bonuses, and VIP bonuses. To give you my honest opinion on these platforms, I consider them to be the industry jewels. Each player has to be part of such a community at least once in their life.

Being able to play and enjoy dozens of offers and promotions might as well be the best thing you can do for your experience as a gambler and your experience as a casino connoisseur as well. At the same time, you can benefit a lot from a financial standpoint. If the operator launches offers frequently, what you can do is try to find a way to claim them regularly and enjoy some incentives, try new games, and explore this industry without risking your own money.

As we were saying before, it’s crucial that you find casino sites that have a license for your jurisdiction. That’s why we try to list them according to the country as well so that players from each country can discover the casinos where they can play legally and safely.
